Although the title of the associated paper suggests that it is based on the ANEW labeled corpus, it is not. The title is simply a wordpun. It was developed independently of the wordlist, and it is not a revision of it. Compared to ANEW, the AFINN word list has more words and includes obscene words. ANEW on the other hand has (besides valence) arousal and dominance for each word and each word has been labeled by several persons and the mean and standard deviation are given. The AFINN was only labeled by Finn Årup Nielsen. Finn Årup Nielsen was in no way involved in development of ANEW. ANEW was developed by Margaret M. Bradley and Peter J. Lang.

"AFINN can be considered as an expansion of ANEW [30], a dictionary created to provides emotional ratings for English words."[1] Actually not. ANEW was not used during the development of AFINN. There might be words in ANEW that is not in AFINN.

"It is important to mention that AFINN does not include any emoticons."[2] This is not entirely precise. Emoticons are available in the Python package AFINN available at Github and PYPI. https://github.com/fnielsen/afinn/

"AFINN. AFINN-111 is an improved version of AFINN-96. The original version was called ANEW (Affective Norms for English Words)" [1]. This is not correct. The original version of AFINN was not called ANEW. The two word lists are independently developed.
